smooth okay I understand to add I2P for privacy since it will probably adds privacy against adversaries not as powerful as national security agencies.
It certainly does that.
I think I did allude to that in my detailed post.
Yes you did.
My issue is that so many people think that means I2P (thus Monero) is safe against the NSA
People are going to think what they think. Many think that Bitcoin is anonymous. i2p has certainly never been sold as NSA-proof and furthermore without knowing the totality of NSA's capabilities you can never correctly describe any implementation of anything as NSA-proof. Even most pure cryptography can't be proven to be secure, and once you get into implementation the potential vulnerabilities explode.
